Matt Koch

Koch made 14 starts and five relief appearances for a banged-up Diamondbacks team last season, filling in capably with a 4.15 ERA. He showed good control, walking just 6.1% of batters, but he managed just a 13.9% strikeout rate. His 5.83 FIP makes a serious step back appear more likely than even a modest step forward, as does his 5.96 ERA in 11 starts for Triple-A Reno. Scouts were never particularly impressed with Koch's repertoire, as his fastball averages just 91.8 mph and none of his secondaries are much better than average. His low walk rate stemmed at least partially from how hittable he is, as opposing batters made contact on 85.9% of swings (compared to 77.0% on average). He'll be a fifth or sixth starter this season and is likely a streamer at best in most formats.
